England's star trio can't fit in the same lineup - what's the verdict?
Having secured six victories out of six, zero goals allowed and a World Cup spot assured before the final rounds, national team coach Thomas Tuchel could suggest he has got all of his big qualifying decisions correct.
Nevertheless, in the preparation for Thursday's home game against Serbia, he initiated discussion when he claimed that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the identical lineup.
"At the moment, if we stick with the system, they cannot play.
"They can but not in the structure, not for the balance that we developed and not in this formation that incorporates wingers who are highly specialized in their positions. We play at the moment with specific numbered positions."
From guaranteed positions to competitive roles
England's creative talents have been utilized out wide for England in the past, but the manager's choices indicate that the Manchester United forward and Arsenal's winger are his primary selections on the left and right flank respectively.
But can Bellingham, Foden and Kane coexist in the lineup?
The previous England manager apparently believed they could.
Bellingham, Foden and Kane featured in every England's seven fixtures at the European Championship in Germany, where Southgate's side fell to the Spanish in the final.
In the 16 games the trio have played simultaneously, England have secured 10 victories, tied three matches and lost three, scoring 36 times and allowing 14 goals.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has employed a four-two-three-one setup that changes shape when England attack.
Morgan Rogers has been the key creative force because of his impressive ball progression, shooting ability and capacity to penetrate the area when the striker drops deep.
Tuchel has mentioned preferring dedicated wide players. The wide attackers play out wide weekly and can maintain possession effectively, engage in one-on-one situations, and arrive in the box to score.
Behind this front four, Tuchel utilizes two central midfielders consisting of a holding midfielder and one with more license to join the forward movement.
What solutions exist for the trio?
Foden and Bellingham would be battling with Cole Palmer, Morgan Rogers and Eberechi Eze for the number 10 role, with Kane expected to lead up front.
Foden could play as the number nine, which potentially could allow both Bellingham and Foden to operate without the captain.
There is an alternative approach all three could coexist effectively and Tuchel suggested it this week.
"With his club, he operates similarly to a number eight or 10, so potentially in future we view him as a number eight," he said.
Foden has been deployed in a versatile central position this season.
That has enabled him to operate from deeper areas and could position him as the advanced playmaker, alongside a holding midfielder.
This would then enable Bellingham to operate as the number 10 and Kane as the striker.
Irrespective of whether Tuchel chooses to configure the team like this at the international competition, what seems encouraging is his readiness to exclude star names in the interest of team harmony.
